Genetic analysis of mutants of Escherichia coli K12 and Salmonella typhimurium LT2 deficient in hydrogenase activity

Abstract
Summary A genetic, study of mutants deficient in hydrogenase activity was performed. In E. coli, the affected gene (hyd) is located at 51 min, between cys C and nal B; in S. typhimurium, it probably lies in the homologous region of the chromosome.
